A stroke is the action of a piston travelling the full length of its cylinder.In a two-stroke engine, one of the two strokes combines primarily the intake stroke and the combustion stroke, while the other stroke primarily combines the compression stroke and the exhaust stroke, though technically since both ports are exposed during both the combustion and compression strokes, some reversion ...
The uniflow method of scavenging has been often used for two-stroke diesel engines in motor vehicles, marine vessels, railway locomotives and as stationary engines. Its drawback is the additional complexity, mass, volume, and cost required to implement the poppet valvetrain (or the additional crankshaft or rocker arms required to control a ...

When the engine reaches a certain speed, the clutch activates, working somewhat like a continuously variable transmission. As the load increases, the speed drops, disengaging the clutch, letting the speed rise again, and reengaging the clutch. If tuned properly, the clutch will tend to keep the speed at or near the torque peak of the engine.
With the clutch pedal completely pressed or a motorcycle's lever pulled entirely towards the driver, there is no direct link between the engine and the driveshaft, so no power can pass from the engine to the driveshaft and wheels. With the pedal entirely released, there is full contact between the engine and the driveshaft, via the clutch plate ...

It evolved directly from the piston port (pre-reed valve intake tract), front drum-braked, five-speed Yamaha 350 cc "R5". [3] The engine is an air-cooled, parallel twin, six-speed (in some markets, such as the UK, the first model was sold in five-speed form), reed valve-equipped intake tract two-stroke engine. The bike is usually referred to as ...
